New to ducks please help

Hello I have a duckling with a broken leg. No bone showing but is limping and barely using the leg. The break is right at the hip and feels minor. Currently the duckling is in a separate cage from the flock with 1 other duckling to keep company. Is there anything I can do to help heal the break besides what I am currently doing? I don't think there is a way to splint it as it is so close to the hip. The ducklings have food and water in the separate cage.

You can try taping the leg up against the body and hold it there for a week or two. If its still broken it will have a hard life and trouble getting out of the water, brushing its feathers it will fall because it can't hold itself up. Maybe see a vet that can tape it? Otherwise maybe put it down but thats up to you. Good luck.
